Gillmore, Quincy A., major-general, was born in Black 
River, Ohio Feb. 28, 1825, was appointed cadet at the United 
States military academy in 1845 and graduated at the head of 
his class in 1849.  The interval between graduation and the 
opening of the Civil war he spent as engineer at Hampton Roads, 
instructor and subsequently treasurer and quartermaster at the 
academy, and in charge of the fortifications in New York harbor.
He was promoted captain of engineers in Aug. 1861, and as 
chief of engineers in the Port Royal expedition and after the 
capture of Hilton Head, S. C., rebuilt the forts and otherwise 
strengthened their position.  Gen. Gillmore gained his greatest 
reputation and recognition as a leading military engineer by 
reducing Fort Pulaski, defending the water approach to Savan-
nah, a strong fortification built on a marshy island that was 
entirely surrounded by deep water.  The reduction of this fort, 
while considered essential to the success of the expedition, 
was regarded as impracticable by the ablest engineers of both 
armies.  Capt. Gillmore, then acting brigadier-general, accom-
plished this by establishing on Tybee island, a mile distant, 
eleven batteries of mortars and rifled guns, which, aimed and 
fired under his minute directions, so shattered the fort as to 
render it untenable.  The bombardment was begun at 8 a. m., 
April 10, 1862, and lasted until 2 p. m. the following day.  
For the exploit Capt. Gillmore was brevetted lieutenant-colonel 
U.  S. A.  He was given important commands in Kentucky in Aug., 
1862, defeated Gen. Pegram at Somerset in March, 1863, for 
which he was given the brevet rank of colonel, and in June, 
1863, he was given command of the Department of the South com-
prising all territory occupied by Union troops on the coasts of 
South Carolina, Georgia and Florida.  He was placed in command 
of the 10th army corps in July, 1863, and commanded it in the 
operations against Charleston, S. C.  Here he again won dis-
tinction and was promoted by brevet to lieutenant-colonel, 
colonel, brigadier-general and major-general in the regular 
army for the capture of Fort Wagner in July, 1863.  For the 
part he took in the bombardment of Fort Sumter, capture of Fort 
Wagner and Battery Gregg, and for operations against Charles-
ton, at long range from the battery known as the "Swamp An-
gel", he was also promoted major-general of volunteers and re-
ceived the commendation of the come mender-in-chief, who said 
of him, "His operations on Morris island constitute a new era 
in the science of engineering and gunnery."  Being transferred 
in 1864 to the command of the 1Oth corps in Virginia, he was 
engaged at the landing at Bermuda Hundred and the action at 
Swift creek, captured the line in front of Drewry's bluff and 
enabled Gen. Butler to withdraw his army to the entrenchment's 
at Bermuda Hundred.  He commanded two divisions of the 19th 
army corps in the defenses of Washington in July of the same 
year, and in 1865 was again ordered to the Department of the 
South, which he commanded until near the end of that year, when 
he resigned his commission in the regular army, and, returning 
to service in the engineer bureau in Washington, was made engi-
neer-in-chief of all fortifications on the Atlantic coast south 
of New York.  He was promoted major U. S. A., in June, 1863, 
lieutenant-colonel in 1874, and colonel, Feb. 20, 1883.  He was 
president of the Mississippi river commission created by Con-
gress in 1879, of the boards of engineers for the improvement 
of the Cape Fear river N. C., and the Potomac river and flats, 
of several boards for important harbor improvements, and was 
one of the judges at the Centennial exhibition of 1876.  Gen. 
Gillmore's works on professional subjects are considered among 
the highest authorities in their class.  He died in Brooklyn, 
N.  Y., April 7, 1888.
